The Palazzo della Ragione is a medieval town hall in Padua. The building, with its great hall on the upper floor, is reputed to have the largest roof unsupported by columns in Europe; the hall is nearly rectangular, its length 81.5m, its breadth 27m, and its height 24 m; the walls are covered with allegorical frescoes; the building stands on arches, and the upper storey is surrounded by an open loggia, not unlike that which surrounds the Basilica Palladiana in Vicenza.
The Palazzo was begun in 1172 and finished in 1219. In 1306, Fra Giovanni, an Augustinian friar, covered the whole with one roof; originally there were three roofs, spanning the three chambers into which the hall was at first divided; the internal partition walls remained till the fire of 1420, when the Venetian architects who undertook the restoration removed them, throwing all three spaces into one and forming the present great hall, the Salone. The new space was refrescoed by Nicolò Miretto and Stefano da Ferrara, working from 1425 to 1440.
A tornado destroyed the roof and damaged the building on 17 August 1756.References:
Built around AD 90 to entertain the legionaries stationed at the fort of Caerleon (Isca), the impressive amphitheatre was the Roman equivalent of today’s multiplex cinema. Wooden benches provided seating for up to 6,000 spectators, who would gather to watch bloodthirsty displays featuring gladiatorial combat and exotic wild animals.
Long after the Romans left, the amphitheatre took on a new life in Arthurian legend. Geoffrey of Monmouth, the somewhat imaginative 12th-century scholar, wrote in his History of the Kings of Britain that Arthur was crowned in Caerleon and that the ruined amphitheatre was actually the remains of King Arthur’s Round Table.
Today it is the most complete Roman amphitheatre in Britain.
